Create enqueued page for Redis implementation

[alishamohanty]

The story will be build in following stages:-

1. Build the entire view of enqueued page. (Most of the components would not be fully functional)

2. Build backend APIs to 2.1 get enqueued jobs in a range 2.2 delete n jobs 2.3 prioritise n jobs

3. Make each component fully functional (add unit tests wherever):

   1. Sidebar
   2. Table view (without select being functional)
   3. Fixed header (ability to filter enqueued jobs)
   4. Modals for destructive actions
   5. Ability to select multiple jobs and perform actions

4. Testing Unit and Integration testing
